[Zope] TypeError when accessing security folder on zope 2.3.3 and win nt

[James]

Hi,
  When I try and click on the security tab by having the root on the left and 
the security tab on the right I get this the following traceback.

I don't have any hotfixes or patchs to the core.
TIA,
Jimbo

The listing below shows the current security settings for this item. 
Permissions are rows and roles are columns.  Checkboxes are used to
indicate where roles are assigned permissions. You can also assign 
<strong><a href="manage_listLocalRoles">local roles</a></strong> to 
users, which give users extra roles in the context of this object and 
its subobjects.

<p class="form-help">  
When a role is assigned to a permission, users with the given role
will be able to perform tasks associated with the permission on this
item. When the <em>Acquire permission settings</em> checkbox is selected
then the containing objects's permission settings are used. Note: the
acquired permission settings may be augmented by selecting Roles for
a permission in addition to selecting to acquire permissions.
